(54) | Dynamoelectric machine |
(57) A dynamoelectric machine having a rotor formed from a continuous strip of ferrous
material and a continuous helically formed conductor thereon. The rotor having a rectangular
cross section is mounted on the periphery of a web member. The web member is axially
mounted for rotation about a frame and supports a fan. The stator of the machine is
axially aligned with the outer circumferential surface of the rotor and provides support
for pairs of permanent magnets and an equal number of pairs of brushes. The field
magnets are positioned to magnetically link with the winding on the rotor. The brushes
are equally and angularly spaced in the frame and operative contact with a commutator
integrally formed with the rotor winding. |
